Updated title on original source: "Jack Dorsey is giving up at least 50% of his stake in Square to help underserved communities"

Update: This post has been updated to correct that Dorsey will commit 10 percent of the entire company, not just his equity as previously stated. In addition, our calculations were off and I regret the error.

This is commendable. Actually intending to making the world a better place (in the non HBO-Silicon-Valley-Show-way).
